Does anybody happen to know the dimension for 1939 or 1940 Mercury wishbones from the center of the axel to the center of the ball? I have a set of bones that this measurement is 44 1/2 " & I am trying to figure what they are from. They are identical to 37-41 Ford bones other than the legnth. They are not "stepped" as are the 42 -48 Ford & Mercury wishbones. Thank you. Bill
